Background: Students will view a Getty Museum video clip regarding the mummification process. Subsequent to the video, time will be allowed for questions and discussion. (The Mummification Process, 2009) https://www.youtube.com/watch?v=-MQ5dL9cQX0
Previous instruction has included data collection and recording and transferring data to graphs for visual representation.

CCSS.ELA-LITERACY.RST.9-10.3 Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks, attending to special cases or exceptions defined in the text.
CCSS.ELA-LITERACY.RST.9-10.7 Translate quantitative or technical information expressed in words in a text into visual form (e.g., a table or chart) and translate information expressed visually or mathematically (e.g., in an equation) into words.
Procedure – READ, ask questions, READ again!, Then start! oLabel each cup, #1-8 oPrepare a data chart for each cup. The chart should include the cup number, beginning mass of the apple slice, desiccant used, final mass, and percentage of mass lost. oDetermine mass of each apple slice, record and place in labeled cup
oPrepare desiccants according to cup label: 1) No desiccant 2) ¾ c baking soda 3) ¾ c Epsom salt 4) ¾ c table salt 5) 50:50 solution of Epsom salt and table salt (mix well) 6) 50:50 solution of table salt and baking soda (mix well) 7) 50:50 solution of Epsom salt and baking soda (mix well) 8) ¼ c Epsom salt mixed with ¼ c baking soda and ¼ c table salt (mix well)
oPour the appropriate desiccant over the apple slice, making sure the apple is completely covered. oPlace the cups out of direct sunlight and let them sit for 6 days. oOne-by-one, carefully measure and record the current weight of the apple slices. Carefully brush off as much desiccant as possible from the apple slices in the solutions prior to measuring. oCalculate and record the amount of mass lost.
oNote qualitative observations for each slice.
Answer the following questions in your Science Journal:
Which salt would seem to work best at making an apple mummy? Use at least 1 visual graph to illustrate your findings.
What was the point of leaving one of the apple slices in a cup without any salt at all?
Where did the moisture in the slices go? How could you confirm this?

o Label each cup, #1-8
o Prepare a data chart for each cup. The chart should include the cup number, beginning mass of the apple slice,
desiccant used, final mass, and percentage of mass lost.
o Determine mass of each apple slice, record and place in labeled cup
o Prepare desiccants according to cup label:
1) No desiccant
2) ¾ c baking soda
3) ¾ c Epsom salt
4) ¾ c table salt
5) 50:50 solution of Epsom salt and table salt (mix well)
6) 50:50 solution of table salt and baking soda (mix well)
7) 50:50 solution of Epsom salt and baking soda (mix well)
8) ¼ c Epsom salt mixed with ¼ c baking soda and ¼ c table salt (mix well)
o Pour the appropriate desiccant over the apple slice, making sure the apple is completely covered.
o Place the cups out of direct sunlight and let them sit for 6 days.
o One-by-one, carefully measure and record the current weight of the apple slices. Carefully brush off as much
desiccant as possible from the apple slices in the solutions prior to measuring.
